Digitizer-workflow --help


(Laurent Aphecetche) #1

Trying to run the digitizer for just one detector and not remembering the available options, I’ve tried :

digitizer-workflow --help

and got a crash. Is that expected ?

Looks like indeed the digitizer-workflow requires that simulation actually ran in the same area in order to work, most likely because options are constructed from the GRP information. @swenzel probably knows more.

Anyways here is the result:

ALICE O2 DPL workflow driver (short help)

Executor options:
  -h [ --help ] [=arg(=short)]          print help: short, full, executor, or 
                                        processor name

  -c [ --completion-policy ] arg (=quit)
                                        what to do when processing is finished:
                                        quit, wait
  -g [ --graphviz ]                     produce graph output
  -t [ --timeout ] arg (=0)             timeout after which to exit
  -D [ --dds ]                          create DDS configuration

  --o2-control                          create O2 Control configuration

  -P [ --plugin ] arg                   FairMQ plugin list

  --infologger-mode arg                 INFOLOGGER_MODE override
  --infologger-severity arg             minimun FairLogger severity which goes 
                                        to info logger
  --child-driver arg                    external driver to start childs with 
                                        (e.g. valgrind)


Global workflow options:
  --tpc-lanes arg (=4)                  Number of tpc processing lanes. A lane 
                                        is a pipeline of algorithms.
  --tpc-sectors arg (=0-35)             List of TPC sectors, comma separated 
                                        ranges, e.g. 0-3,7,9-15
  --onlyDet arg (=none)                 Comma separated list of detectors to 
                                        accept. Takes precedence over the 
                                        skipDet option. (Default is none)
  --skipDet arg (=none)                 Comma separate list of detectors to 
                                        skip/ignore. (Default is none)
  --tpc-reco-type arg                   Run TPC reco workflow to specified 
                                        output type, currently supported: 
                                        'tracks'
  --configKeyValues arg                 Semicolon separated key=value strings 
                                        (e.g.: 'TPC.gasDensity=1;...')

Thanks for the quick (reply and fix) !
